Thermal conversion of biomass into fuels is the major focus of research at our NSF-CREST Bioenergy center. Biomass gasification produces syngas (CO:H2) that is converted into fuels in the presence of catalysts by Fischer-Tropsch (F-T) synthesis. Silicon microchannel microreactors (50 μm x 100 μm) provide a relatively simple and rapid means for screening F-T catalysts. While the highest conversion of CO, ~78% at 220 °C, can be obtained by adding only 0.4 wt.% Ru to Fe-Co/SiO2, the stability studies with each individual catalyst show that Co is more stable than Ru or Fe .
We are also developing novel steam reforming catalysts for H2 production that is purified using a membrane for fuel cell applications. In order to understand the significance of metal-support interaction on pure H2 production, we have synthesized several high surface area mesoporous TiO¬2 and SiO2 (MCM-41) supported Cu, Co, Ni, Pd, Sn and Zn catalyst using one-pot procedure and tested for steam reforming of methanol (SRM). The catalysts exhibited surface area, and pore sizes in the range of 99-1039 m2/g, and 2.63-4.69 nm, respectively, based on the nature of the metal and the support. Remarkable differences in activities of M-TiO2 and M-MCM-41 catalysts based on metal-support interactions and metals are observed [2-4]. The steam reforming (SR) studies have now been extended to glycerol. The highlights of our on-going SR studies at 650 °C using MCM-41 and SBA-15 supported Co- and Ni-nanocatalysts and their stability studies will be presented.
